Data Center Siting Rules Are Up for Decision
Salem has scheduled a hearing on a zoning interpretation that could affect an unapproved data center campus. Separately, voters were scheduled to decide 41 local data center measures yesterday, although results are not yet available in the reporting reviewed.
Both developments put specific approval rules in focus. Neither yet establishes a change to a project’s status.
Salem City Council will consider the proposed zoning interpretation on November 9, the Salem Business Journal reports. It would treat AI and hyperscale data centers as excluded under existing rules. The city considers the application for Oakline at Mill Creek, a proposed two-building, roughly 600,000-square-foot campus, incomplete. The interpretation has not been adopted.
Ballotpedia counted 41 local measures scheduled for November 3 across 10 states, including 21 in Ohio. Of the total, 28 would restrict development and 13 would facilitate it. That clarifies the mix of measures discussed in the previous briefing, but not their outcomes or legal effects.
Data Center Knowledge examined President Trump’s proposal that new large data centers generate their own electricity and return surplus power. Industry experts told the publication that around-the-clock reliability, permitting, fuel access and equipment availability make a combination of onsite and grid power more practical than fully off-grid supply. The proposal is not an enacted requirement.
Key Points
- The local ballot measures do not amount to a single national verdict on data center development: they would change rules in different jurisdictions and in different directions.
- Onsite generation can change a project’s power strategy without eliminating delivery constraints. Fuel, permits, equipment and grid arrangements still need to work together.
Implications
For Oakline, the distinction between interpreting existing zoning and creating a new restriction could affect the procedures governing its path forward. That legal question remains contested.
Developers and investors should distinguish exposure to proposed rules from an adopted restriction, and a power proposal from an executable supply arrangement.
Watchpoints
Watch
Verified results for the November 3 measures, especially in Ohio, and the effective dates and site-level consequences of any binding changes.
Watch
The outcome of Salem’s November 9 hearing, the legal mechanism adopted if any, and changes to Oakline’s application status.
Watch
Whether the onsite-power proposal becomes a formal requirement, and whether projects demonstrate workable generation, fuel and grid arrangements.
Fallout
Local approval decisions are approaching, while the practical limits of onsite power remain under discussion.
Salem zoning and Oakline
A contested interpretation of existing zoning could affect an unapproved data center proposal.
Fresh developments
Salem Business Journal reported that the city council will consider the interpretation at a November 9 hearing. The city considers Oakline at Mill Creek’s application incomplete.
Why we noticed
Whether the measure clarifies existing rules or imposes a new restriction could matter to the procedures required. No exclusion or project rejection has been established.
Watch for:
- The hearing outcome and any change to Oakline’s application status.
Local ballot measures
Measures scheduled in 10 states could alter local development conditions, but their results remain unverified in the available reporting.
Fresh developments
Ballotpedia identified 41 measures scheduled for November 3: 28 restrictive and 13 facilitating development. Ohio accounted for 21.
Why we noticed
The split matters: outcomes must be assessed jurisdiction by jurisdiction rather than treated as a uniform vote for tighter restrictions.
Watch for:
- Verified results, effective dates and consequences for specific projects.
Onsite power
Self-generation is being discussed as a way to supply new data centers, but it has operational constraints.
Fresh developments
Data Center Knowledge reported experts’ assessment that hybrid onsite and grid supply is more practical than fully off-grid operation.
Why we noticed
Reliable generation depends on permits, fuel and equipment as well as the facility’s relationship with the grid. Trump’s proposal has not become a requirement.
Watch for:
- Any formal implementation and evidence of executable power arrangements.

Final Thought
For developers, the distance between a proposal and a usable approval or power supply remains the critical distinction.
